Yoga studio 3:4 portrait promo, 8 seconds: models and price

A 3:4 portrait promo works on wan-3.0 ($1.00 for 8 s at 720p), minimax-h3 ($0.60 at 768p), seedance-2-fast ($2.42) and seedance-2.5 ($4.63). gemini-omni-flash-1.1 lists only 16:9 and 9:16 and kling-3 lists 16:9, 9:16 and 1:1, so neither takes 3:4. Source: Video Router, read 2026-10-06.

3:4 is the shape of a feed-grid poster and many studio-window displays. If you need true phone-vertical instead, use 9:16.

What does the promo cost?

Eight seconds, 3:4.

What does the request look like?

Set aspect_ratio to 3:4 explicitly.
